  1. Since we're on the topic' date=' what material is the stock 240Z gas tank made out of?

     

    I'm thinking about welding some stainless steel bung adapters to the bottom and have AN lines just draw out of that.

     

    Crap, I better search or else I'll get yelled at.

    Like Stony suggested get a sump. I was planning on doing that while I'm doing all the other mods. Aeromotive has a sweet one, but it's about $150. Or I can get a normal sump for about $70.

     

    I know the tank is made out of sheet metal, and the gauge looks to be about 20 or 22.

  2. Hold your wallet in your own pocket mister money bags!

     

    I guess the real questions is when do you stop. When I was figuring out this swap I thought the Walbro 255, and some new lines would be all I needed. And then the monster jumped out and said "for a few more dollars you can the Aeromotive A1000, and it will be the last pump you need to get!" So I said great idea, I hate wasting money on something that I'll be replacing soon any way. So of course I need to get some High flow filters to protect my investment, and I midas well get a FPR while I'm at it. And I guess change all the lines and fittings.

     

    Man that stuff adds up fast. LOL

  3. It seems like a lot of work to go through for not much more gain in performance. But I guess it depends what your going to use the car for. ITB's are great for auto-cross type events, and the TB is great for Drag. Either way there is not much of a difference, until you start making Mega HP.

  4. There might be some kind of side feed fuel cell, but I'm not sure how well they work or if they exist.

     

    I've looked, and it seems that it's only a custom cell. As in $$$$$$$$$$. If I could find a cell with an off center filler I could use a 45*neck, and a remote filler from Summit. I'm already going to be spend $1K on the fuel system, so whats another $300 or so.:icon45:

  5. the welding part is easy, just be careful with the thin metal, dont let it get too hot. if your going to take out the wheel well and put on an extension why not just put in a fuel cell?

     

    I want to keep the stock filler location. And from what I've seen most if not all of the cells fill in the middle of the tank. I would need to drop the cell pretty low to have enough clearance to run a filler neck. A fuel cell would be the simplest way to get it done, the way I want. Do you know of a way to run the filler from the stock location? The only examples I've seen run the tube through the cargo area, which I don't want. Another thing is that I also want to keep the stock gauges, and the GM sending units won't work with the Datsun fuel gauge.

  6. Certain systems have different ways of doing this. I'm still confused on the whole topic.

     

    As for me' date=' I plan to plug all but 1 of the vents on top of the gas tank. I'm still going to be concerned with the return line and the surge tank though. I might route the return from the surge tank, back to the original gas tank.[/quote']

     

    The vent lines on the tank are there to allow the fuel to fill all the way up. If you look at your tank you will see that it has a few high spots, (so that it can conform to the floor of the car.) and the vent lines are connected there. You might loose 1/2 to 1 gallon of capacity if you plug up most of the lines.

     

    Right now I'm toying with the idea of heavily modifying my 260Z tank. I'm going to divot the lower pass side, to allow for a twin exhaust. And then run new Exit and return lines of the size I want. -8 & -6. I might also remove the tire well, and weld in an extension on the top of the tank. (for more capacity) All of this will require me to split the tank open, and of course learn how to weld. LOL

  7. If your smelling gas it's because you need to replace those 30yr old + lines. If your getting rid of the Evap controll system you can loose it. But as of yet I haven't heard a good reason to get rid of the Evap Sys.

  8. Not to bring your hopes down or anything' date=' but rarely...... and almost never, do I ever have a problem free session when working on ANY car. So i can almost gaurantee your gonna run into a few head scratchers, no matter how much your study. its just the nature of working on cars.

     

    But thats ok because you have us at hybrid for help![/quote']

     

    Your not going to bring my hopes down. Rarley does anything work out exactly as planned, no matter how much you plan ahead. But I figure when I run into the problems I will hopefully have some idea of what to do next.

     

    With my job I have more time to plan, and less time to actually do it. And currently I'm useing my Z as a dailey driver. So the down time has to be minimal. I'm going to start the prep work while the car is still on the road. I figure the actual Engine/Tranny install will take a day or 2. Final plumbing a day. Elec 1-3 days. Plus head scrathing 5-7 days.

  9. He doesn't even have the motor yet (to my knowledge). Oh yeah and...

     

    bump

     

    Hey no motor yet. It needs to thaw out around here first. LOL Working in 30 degree weather is not fun. Right now I'm gathering all the parts and information I need. I want to know what I'm doing before I start. I won't have time to mess around scratching my head' date=' once I start. The engine will be last (Probably at the end on March) I want the engine in & running within 2 weeks of starting the swap.

     

    I think I have all of the mechanics of the swap worked out in my head. The Elec is still a bit sketchy. But I'm working through it. The plan will be to open up the stock S30 harness, splice in the RB, and re-wrap it. Now just got to figure what wire to splice where.

     

     

    Hey Ed,

     

    if you look under the dash, on the passenger side, there is a bunch of harnesses that connects the stock s30 engine harness to the chassis. go to the harness that has the start signal wire on it, i think it has like 6-8 prongs on it, and i beleive the start signal wire is black with white stripe. take a test light and try the other wires on that harness for power with the turn of the keyswitch. that was the most convienient place that i found to splice into because all the rest of the wires that i needed to splice into were in that general area. for ex, the start sig, the stock s30 coil power wire ( i used for RB IGN power) , water temp wire that goes to gauge, and ecu power, etc.

     

    basically everything you need to wire the RB into s30 are under the dash, passenger side, just start playing with a volt meter.

     

    Thanks for the info
